The One | Hello Swim

Dive in with confidence with The One, our ultimate one-piece black leakproof period swimsuit.  

Sleek, discrete with coverage where it matters, the timeless crossback design of The One will make this your go-to swimsuit every time.  No need for tampons or pads, this period-proof swimsuit has an absorbent gusset that wicks period blood away and locks it in.

Both our models are wearing size Medium. They'd normally wear a size 12.

Choose your normal size. Period swimwear works best with a snug fit so if you are between sizes, we'd recommend sizing down.

How Do They Work?

Hidden inside The One swimsuit is clever technology to let you swim with confidence when you’re on your period.

The One swimsuit contains multiple built-in layers designed to absorb menstrual blood while keeping water out. The top layer of the gusset will wick moisture away from the body and into the absorbent core which is designed to lock it in. A waterproof outer layer then prevents anything from leaking out. 

The One Swimsuit is designed for a light to medium flow.
